SSN misuses

The most misused SSN of all time was (078-05-1120). In 1938, wallet
manufacturer the E. H. Ferree company in Lockport, New York decided
to promote its product by showing how a Social Security card would
fit into its wallets. A sample card, used for display purposes, was
inserted in each wallet. Company Vice President and Treasurer
Douglas Patterson thought it would be a clever idea to use the
actual SSN of his secretary, Mrs. Hilda Schrader Whitcher.
